Although your timing does appear off of days/nights you intend to stay, the word camping raises some flags. This topic has been discussed to the brink this summer with one good link being here: http://www.mountwashington.org/forum...hlight=camping But in case you do not want to read that all, these are the rules and regs that you need to know:
Presidential Range-Dry River Wilderness
Wilderness regulations, intended to protect Wilderness resources and promote opportunities for challenge and solitude, prohibit use of motorized equipment or mechanical means of transportation of any sort. Camping and wood or charcoal fires are not allowed within 200 ft. of any trail except at designated campsites.
Hiking and camping group size must be no larger than 10 people. Camping and fires are also prohibited above the treeline (where trees are less than 8 ft. tall), except in winter, when camping is permitted above the treeline in places where snow cover is at least 2 ft. deep, but not on any frozen body of water. Many shelters have been removed, and the remaining ones will be dismantled when major maintenance is required; one should not count on using any of these shelters.
Forest Protection Areas
The WMNF has established a number of Forest Protection Areas (FPAs)?
formerly known as Restricted Use Areas?where camping and wood or charcoal fires are prohibited throughout the year. The specific areas are under continual review, and areas are added to or subtracted from the list in order to provide the greatest amount of protection to areas subject to damage by excessive camping, while imposing the lowest level of restrictions possible. A general list of FPAs in this section follows, but since there are often major changes from year to year, one should obtain current information on FPAs from the WMNF.
(1) No camping is permitted above treeline (where trees are less than
8 ft. tall), except in winter, and then only in places where there is at least
2 ft. of snow cover on the ground?but not on any frozen body of water,
and not on the east face of Mt. Washington's summit cone from Boott
Spur to Nelson Crag (the area above Tuckerman and Huntington Ravines,
including the Alpine Garden area). The point where the above-treeline
restricted area begins is marked on most trails with small signs, but the
absence of such signs should not be construed as proof of the legality of
(2) No camping is permitted within a quarter mile of any trailhead,
picnic area, or any facility for overnight accommodation such as a hut,
cabin, shelter, tentsite, or campground, except as designated at the facility
itself. In the area covered by Section 1, camping is also forbidden within a
quarter mile of Glen Ellis Falls
I would close by saying that most of Mt Washington is a day trip. I would say if you are trying to stretch it out for muli days, set up a base camp at one of the designated areas in either the great gulf or tuckermans and make some day trips. It lightens your load up the cirques and still allows for legal camping "on" the mountain.
